My truck went in for a recall repair of the passenger

My truck went in for a recall repair of the passenger airbag. During the repair the dash was cracked. I, as the owner, noticed the crack within 1 mile of leaving the dealership at night. I brought it back to the service bay immediately. During follow-up to get the broken dash fixed, there was an inference made that the crack was already there before the repair was made, and one of the managers basically called my wife a liar during the exchange. This made her extremely upset. We continue to try and seek resolution to this issue.

I grew up in Rib Mountain, WI but I've been in this area since 2002. I grew up playing hockey and I'm happy to say I still have all my teeth! When I'm not at the dealership, I enjoy spending time with my wife and my dog and enjoy vacationing. Our goal at Heiser is to provide top notch customer service and make you feel like you're part of the family.

Prior to getting into the auto business, I was a stay at home mom and a substitute teacher for 12+ years in West Bend, WI. 3 years ago, I came to Heiser Chevrolet Cadillac to look for a car for my daughter. The car that I came for on Friday, was sold on Saturday... (I went home to think about it).... It prompted me to say, "if cars sell this fast I'm in the wrong business", (just kidding of course, I loved my teaching job)... After numerous calls from management and my sales reprehensive Samantha, I joined the Heiser team! I love it! I pride myself on integrity, not being high pressure, you tell me what you need and want and I will make sure you find what you are looking for... I know you will not only be completely satisfied with me, but my whole Heiser team. I'm looking forward to working with you and welcoming you to our Heiser family!

The is a problem when you take your vehicle in for

The is a problem when you take your vehicle in for service. when a person says I think my lifters are bad and they say nope you are fine Then 2 weeks later your lifters are getting replaced. I learned you need to see what the the service writer wrote down because it’s like playing the game of telephone. You can say what is the problem but the person doesn't hear a word you said. My son asked for all records and then met the mechanic. The mechanic can only look at what the service writer puts in. When I read what they typed in it is not what I said was my issue. When I’m told to take my vehicle to another dealer because we apparently do not make you happy, I was dumb founded. Sherry my sales lady moved heaven and earth to help me. She asked the mechanic to talk with us, I only have great things to say about her. This lease I’m am counting down the days to turn In my keys. I wanted out of it yet management didn’t care.

Did not feel quotes were good. I felt like I was negotiating a car deal and it was a sale deal or pitch. When I work with my favorite car repair shop, they diagnose, tell me the cost, and don't try to upsell me. I don't plan to come back due to overcharge . The cost was so high and my husband did the repair for under $100.
